Editing a raw image (launched from Lightroom) in Photoshop CC 14.1.2 disables GPU and won't open file in Photoshop

Just updated to Photoshop CC 14.1.2 and Lightroom 5.2 and now Photoshop won't recognize my GPU. When I try edit a file in Photoshop by launching it from Lightroom I get a dialogue box from Lightroom saying "The file could not be edited because Adobe Photoshop CC could not be launched." I'm running a 2011 MacPro on OS X 10.8.5 with 2 Quad-Core Intel Xeon processors, 32GB of RAM and an ATI Radeon HD 5770 graphics card. PLEASE HELP!
